Isn't that song the greatest? Actually since it's not an a priori concept there's some semblance of esoteria. So I'll elaborate. It's a song title by an artist called Tommy Tutone.

But that's not the point of this thread. Oh no. The point is abusing the esoteria:

Ladies: if you have ever been asked to give out your phone number, have you ever used the above phone number? If so, how did it go? If not, why aren't you out there giving out your phone number as 867-5309?

Mandies: have you ever received said phone number? Did you/do you now know what it means? If you didn't, can I laugh at you?
